[ANN] Haskell Cheatsheet v1.0. Justin Bailey
announced
a "cheat
sheet" for Haskell, a PDF that tries to summarize Haskell 98's syntax,
keywords and other language elements.

Salsa: A .NET Bridge for Haskell. Andrew Appleyard
announced
the first
release of Salsa,
an experimental Haskell library that allows Haskell programs to access .NET
libraries. Salsa operates by loading the .NET runtime into your Haskell
process and using the FFI (and run-time code generation) to marshall calls
between the .NET and Haskell runtimes. It includes a code generator and a
type-level library (which uses type families) to provide type-safe access
to .NET libraries in Haskell with C#-style method overload resolution
and implicit conversions.

maccatcher-1.0.0. Jason Dusek
announced
the maccatcher
package, which obtains a MAC address on *NIX and Windows.

Call for Contributions - Haskell Communities and Activities Report,
November 2008 edition. Janis Voigtlaender
sent out call
for contributions to the 15th edition of the Haskell Communities &
Activities Report. The submission deadline is 31 October 2008. If
you are working on any project that is in some way related to Haskell,
please write a short entry and submit it. Even if the project is very
small or unfinished or you think it is not important enough -- please
reconsider and submit an entry anyway!

Data.IVar 0.1. Luke Palmer
announced
the release of the Data.IVar
module, which provides write-once variables that can be blocked on in
parallel. Unlike other implementations, Data.IVar does not use thread
racing, since empirical tests have shown that the GHC scheduler is not
quite good enough to handle thread-racing efficiently.

A wiki page for managing the 6.10 handover. Don Stewart
announced
a wiki
page to help with the transition to GHC 6.10. It collects the 7 or so
known issues that break code with GHC 6.10. Please feel free to clean up,
and especially add techniques for handling each change.

Graphalyze-0.4 and SourceGraph-0.2. Ivan Lazar Miljenovic
announced
the release of version 0.4 of the Graphalyze
library and version 0.2 of the SourceGraph
programme. SourceGraph is a programme designed to help you analyse the
static complexity of your Haskell code when represented as a graph. These
releases fix the bugs reported by Gwern Branwen, Magnus Therning, and
Christopher Hinson.

darcs 2.1.0. Eric Kow
announced
the release of darcs
2.1.0. This version provides over 20 bug fixes and 7 new features
since darcs 2.0.2. Most notably, the darcs-2 repository format is now the
default, there is better HTTP support, and a longstanding 'pending patch'
regression has been fixed.

Yi 0.5.0.1. Jean-Phillipe Bernardy
announced
the 0.5
release of Yi, a text editor written and extensible in Haskell. The
long-term goal of the Yi project is to provide the editor of choice for
Haskell programmers.

Discussion

OT: Haskell desktop wallpaper?. Magnus Therning
asked
for Haskell-themed desktop wallpapers, and the community responded with
quite a few nice images.

A general question about the use of classes in defining
interfaces. S. Doaitse Swierstra
asked
about the feasibility of including top-level functions implemented using
Applicative combinators as class methods with default implementations,
to allow for the possibility of giving them more efficient implementations
in specific instances.
